During the show, Ferruh discusses what causes could have led to the infamous Equifax hack and the data breach of hundreds of millions of records of cardholder data. Even though it was thought that a deserialization vulnerability in the REST plugin of Apache Struts was the main cause, an OGNL Expression Injection (CVE-2017-5638) published in March was the root cause for the breach. Therefore our Security Researcher, Sven, gave a live demo of how to find and exploit several OGNL expression vulnerabilities in Struts.

During the demo, Sven also used Netsparker Web Application Security Scanner to highlight how easy it is to automatically find these types of vulnerabilities when you use the correct tools. Watch the full Hack Naked News episode #143.
